tests: Add baseline tests for automatic PHB usage These tests demonstrate that, while it's now possible for the user to create PHB explicitly and manually assign devices to them, libvirt still defaults to extending the guest PCI topology using PCI bridges and making suboptimal device placement choices. The next few commits will improve on these behaviors and the tests outputs will automatically be updated to reflect this.

qemu: Use PHBs when extending the guest PCI topology When looking for slots suitable for a PCI device, libvirt might need to add an extra PCI controller: for pSeries guests, we want that extra controller to be a PHB (pci-root) rather than a PCI bridge.

qemu: Isolate hostdevs on pSeries guests All the pieces are now in place, so we can finally start using isolation groups to achieve our initial goal, which is separating hostdevs from emulated PCI devices while keeping hostdevs that belong to the same host IOMMU group together.
